Normal Human Epidermal Melanocytes 2 (NHEM 2)
Primary human epidermal melanocytes isolated in PMA-free Melanocyte Growth Medium M2 from the epidermis of juvenile foreskin.
Primary Normal Human Epidermal Melanocytes (NHEM) are isolated from the epidermis of juvenile foreskin. Melanocytes are located in the stratum basale, but branch out between the keratinocytes in suprabasal layers. About 5-10 % of the cells in the epidermis are melanocytes.
The main purpose of melanocytes is the production of melanin, the protein responsible for the pigmentation of the skin, eyes, and hair. Melanin protects the cells in the skin and in deeper layers from the hazardous effects of UV radiation. It is produced and stored in melanosomes, which are located close to the melanocyte membrane, but it can also be transferred to neighboring keratinocytes.
Our Normal Human Epidermal Melanocytes 2 are isolated using the serum-free and PMA-free Melanocyte Growth Medium M2.
Since PMA is a tumor promoting mitogen, it can interfere with experimental approaches. Therefore, we recommend using cells isolated in Melanocyte Growth Medium M2 and also using this medium for cultivation.
Normal Human Epidermal Keratinocytes (NHEK) and Normal Human Dermal Fibroblasts (NHDF) from the same donor are available on request.
- Our NHEM 2 are now also available from HLA-typed donors.

NOTE: We will be discontinuing our Normal Human Epidermal Melanocytes 2 (NHEM 2), effective October 2024.
However, we are pleased to offer our Normal Human Epidermal Melanocytes NHEM M3 as a high-quality alternative for your research needs.
